Jellyfish are composed of cells just like any other organism is.
A boneless animal is often referred to as a "jellyfish." Jellyfish lack a true skeleton or bones, as they are composed mainly of a gelatinous substance and have a simple body structure. Other examples could include certain types of worms and sponges, which also do not possess bones.
The heaviest animal without bones is the jellyfish, specifically the species known as the lion's mane jellyfish (Cyanea capillata). This jellyfish can weigh over 200 kilograms (440 pounds) and has a bell diameter that can reach up to 2.5 meters (8 feet). Unlike vertebrates, jellyfish are composed mainly of water and have a gelatinous structure, allowing them to achieve significant sizes without a skeletal system.
The sun is composed of about 73% Hydrogen, 25% Helium, and 2% Oxygen... This means that the sun is mainly composed of Hydrogen
Mainly squid. Sea Turtles and the bearded goby fish also eat jellyfish.
No,they do not lay eggs.They reproduce from budding mainly.
Possible, but not likely. Jellyfish eat whatever they can catch in their tentacles, mainly smaller fishes, eggs and larvae of sea creatures and zooplankton. The larger species of jellyfish eat crustaceans and other jellyfish.
Yes They mainly live in the waters of Japan but fishermen are not happy because they find it hard to fish and the jellyfish break the nets.
Dinosaur bones are made of hard, durable material like calcium phosphate, which is more resistant to decay than the soft tissue of jellyfish. Jellyfish are composed mainly of water and soft tissues that decompose quickly, making it harder for them to fossilize. The conditions needed for fossilization, such as rapid burial and protection from scavengers, are more likely to occur for hard, mineralized bones than soft-bodied organisms like jellyfish.
Nitrogen
Jellyfish are composed of over 90% water
A jellyfish's body is composed of 95-98% water. This high water content helps jellyfish stay buoyant and move easily through the water.
